CISSOID CHT-GEM6489A-TDFP16-T

Product Info

General Description

CHT-OPAL is an ultra high-precision, dual operational amplifier designed for applications that require very low offset and very low noise. Both amplifiers can be configured as a differential amplifier or as an instrumentation amplifier (combined with a third, external amplifier cell and with external resistors). Key features include single 5V nominal power supply and rail-to-rail inputs and outputs. Best-in-class precision on the full temperature range -55°C to +225°C encompass low input offset (internally compensated) and low noise. The internal circuitry uses a clock that is internally generated.

There is a spread-spectrum mode for this clock. The user can decide not to use this internal clock and rather provide it from external circuitry (e.g. for synchronization purposes).

CHT-OPAL also features a Stand-by mode that disables the two Op Amps and place the circuit in a low power consumption mode when the function is not needed.
